Inner ear MRI enhancement based on three dimensional-real IR sequence in patients with Meniere's disease after intravenous gadolinium injection: Comparison of different doses used and exploration of an appropriate dose.

Intravenous injection of gadolinium in a single dose may be unbefitting for the inner ear imaging based on 3D-real IR MRI, both the applications of gadolinium in 1.5 times and double doses can have a good perilymphatic enhancement effect of inner ear. In order to minimise the use of dose for avoiding or mitigating the adverse reactions and renal damage, 1.5 times dose may be preferred in clinical practice.
